When the colder months roll in, it’s time to start thinking about protecting your jet ski. Winterizing isn’t just about keeping it in good shape—it’s about making sure it’s ready to hit the water as soon as the weather warms up. Trust me, a little effort now can save you from costly repairs and headaches later.
I’ve learned that taking care of your jet ski during the off-season is just as important as enjoying it during summer. From preventing engine damage to keeping the exterior in top condition, there are a few key steps that make all the difference. If you’re not sure where to start, don’t worry—I’ll guide you through it.
Why Winterizing Your Jetski Is Important
Winterizing your jet ski protects its engine and internal components from damage caused by freezing temperatures. Water left inside the engine or cooling system can expand and crack parts when it freezes, leading to costly repairs.
Corrosion and rust can develop over the winter if your jet ski isn’t properly prepared. Moisture remaining in the fuel system, exhaust, or other areas creates an ideal environment for these issues, which harm performance and reduce the lifespan of components.
Fuel deterioration is another risk during extended storage. Without stabilizers, fuel breaks down and forms deposits that clog fuel lines and carburetors, making startup and performance unreliable when warmer months return.
Exterior damage, such as fading or cracking, can occur if the jet ski is inadequately stored. Exposure to cold, moisture, and fluctuating weather conditions stresses materials, especially in uncovered or poorly sealed areas.
By winterizing, I avoid these problems, keep my jet ski in top condition, and ensure hassle-free operation once the season changes.
Tools And Supplies Needed For Winterizing
Preparing the right tools and supplies makes winterizing your jet ski efficient and thorough. Here’s what I use:
- Socket Wrench Set: Useful for removing battery connections and other engine components.
- Marine-Grade Antifreeze: Prevents internal water from freezing, protecting the engine.
- Fuel Stabilizer: Keeps the fuel fresh and prevents clogging in the system during storage.
- Fogging Oil: Shields the engine’s internal parts from corrosion.
- Water Hose and Flush Kit: Cleans out residual water from the cooling system.
- Battery Charger: Maintains battery health through the off-season.
- Marine Cleaning Supplies: Includes soap, sponges, and protectant spray for cleaning and UV protection.
- Protective Cover: Safeguards the jet ski from dust, moisture, and other elements during storage.
Having these items on hand ensures every winterizing step is covered efficiently and helps prevent potential damage to your jet ski.
Step-By-Step Guide On How To Winterize A Jetski
Follow these steps to keep your jet ski in excellent condition during the offseason. Proper winterization ensures the engine, fuel system, and exterior remain protected.
Cleaning And Flushing The Watercraft
I clean the hull and deck thoroughly to remove salt, algae, and debris. Using marine-friendly soap, I ensure all surfaces are spotless, reducing the risk of corrosion during storage. To flush the jet ski’s cooling system, I connect a water hose to the flush port and run fresh water through the system for two minutes, eliminating salt and contaminants.
Draining Water From The Engine
After flushing, I start the engine for 15–30 seconds while tilted slightly at the rear. This process expels any residual water from the engine and cooling system to prevent freezing damage. Ensuring all water is removed is vital to avoid internal cracks.
Adding Fuel Stabilizer
I add the recommended amount of fuel stabilizer to a full tank. Running the engine briefly allows the stabilizer to circulate through the fuel lines and system. This step prevents fuel separation and varnish buildup during long-term storage.
Lubricating The Components
Spraying fogging oil inside the engine intake and spark plug holes protects components from rust and corrosion. I also lubricate external moving parts, such as cables and hinges, with a water-resistant lubricant for smooth operation.
Removing The Battery
Disconnecting and removing the battery prevents it from draining over winter. I clean the terminals and store the battery in a cool, dry area on a maintenance charger to retain its lifespan.
Protecting The Exterior
I wax the hull to create a protective layer against moisture and UV damage. Covering the jet ski with a durable, breathable marine cover shields it from dirt, pests, and harsh weather conditions, ensuring it stays in pristine condition.
Common Mistakes To Avoid When Winterizing A Jetski
- Skipping the Engine Flush
Neglecting to flush the engine allows salt, debris, and algae to remain, causing corrosion and blockages. Always flush the system with fresh water after every use, even if the watercraft was used in freshwater.
- Failing to Drain Residual Water
Leaving water inside the engine increases the risk of freezing and expanding, which can crack parts. Completely drain all water from the cooling system before storing the jet ski for winter.
- Incorrect Fuel Stabilizer Use
Using the wrong amount of stabilizer or not circulating it through the system can result in gum and varnish buildup. Add the correct amount to a full tank and run the engine briefly to ensure even distribution.
- Ignoring Battery Maintenance
Leaving the battery connected or uncharged during storage can shorten its lifespan. Disconnect the battery, store it in a cool, dry place, and keep it on a maintenance charger to preserve health.
- Forgetting to Inspect Key Components
Overlooking belts, hoses, and clamps can lead to unnoticed wear or damage. Examine these parts closely before winterizing, replacing any that are cracked or weakened.
- Skipping Fogging Oil Application
Not using fogging oil leaves engine components susceptible to rust. Spray fogging oil into the carburetor or air intake while the engine is running, maintaining lubrication during storage.
- Improper Covering
Using a torn or poorly fitting cover doesn’t protect against moisture, UV rays, or pests. Invest in a durable, marine-grade cover that fits securely over the jet ski to shield it properly.
- Underestimating Storage Conditions
Storing the jet ski in a damp, unprotected area invites rust, mildew, and rodent infestations. Choose a clean, dry, and enclosed space or use a high-quality protective shelter.
- Neglecting the Exterior
Skipping waxing or cleaning exposes the hull to potential UV damage, grime buildup, and cracking. Wax the jet ski and clean all exterior surfaces before storage to maintain its appearance.
- Rushing the Process
Completing winterization steps hastily can lead to overlooked details. Set aside sufficient time to follow every step carefully, ensuring thorough protection for the jet ski.
Storing Your Jetski Properly For Winter
Proper storage keeps a jet ski protected from damage and ready for use in warmer months. Location, preparation, and covering all contribute to effective storage.
Choosing the Right Storage Location
Store the jet ski in a dry, climate-controlled space like a garage or storage unit. Outdoor storage is acceptable if it’s on a raised surface and fully covered to prevent moisture and UV exposure. Avoid storing it near heat sources or damp areas to prevent damage.
Positioning the Jet Ski
Use a sturdy trailer or storage stand to keep the jet ski level. Ensure the drain plugs are removed to allow any water to escape. Tilting the front slightly upward helps prevent pooling from condensation.
Securing the Cover
Choose a marine-grade cover designed for jet skis. Cinch the cover to prevent it from dislodging during wind or harsh weather. Ensure it’s breathable to reduce trapped moisture, which can cause mold or mildew.
Checking Throughout Winter
Inspect the jet ski every few weeks for signs of wear, pests, or moisture accumulation. Tighten the cover and verify the condition of the surroundings to catch potential issues early.
Conclusion
Taking the time to winterize your jet ski properly is one of the best ways to protect your investment and avoid unnecessary headaches when the next season rolls around. It’s all about giving your watercraft the care it needs to endure the harsh winter months and stay in great shape.
By following the right steps and avoiding common mistakes, you’ll not only prevent costly repairs but also ensure your jet ski is ready to hit the water as soon as the weather warms up. A little preparation now goes a long way toward keeping your jet ski running smoothly for years to come.
